Last month’s Brad Paisley concert at Aaron’s Amphitheatre was a big hit.

A couple of teenage girls needed to use the ladies room afterwards, but didn’t want to wait in the long lines. They so decided to head into the woods behind a nearby gas station.

Atlanta police say it was there a strange man approached the girls, claiming to be an undercover cop.

But he wasn’t.

“He told both of them to come with them and go to a next door building,” said Atlanta police officer John Chaffee. “At that point he tried to pat down the girls.”

Chaffee says the suspect also ordered the girls to the ground and asked them to take off their clothes. 

They refused and were able to run to a real police officer to get help.

The victims are 16 and 17 years old. They were not hurt.

The alleged assault happened Sept. 15. But now police have a detailed sketch of their suspect.

He is described as a white male, 35-40 years old, about 5-feet-10 to 6-feet tall. He also has a scruffy, unshaven face, according to police.

Anyone with information on the suspect is asked to contact investigators at 404-546-4260 or Crime Stoppers at 404-577-8477. Callers can remain anonymous and may be eligible for a reward of up to $2000.
